Figure 5From: Inhibition of porcine reproductive and respiratory syndrome virus infection by recombinant adenovirus- and/or exosome-delivered the artificial microRNAs targeting sialoadhesin and CD163 receptorsDetection of PRRSV ORF7 copy numbers in rAd-transduced and/or exosome-incubated PAMs. Primary PAMs were transduced with single or double rAds and/or incubated for 48Â h with single or double amiRNA-containing exosomes. The cells were infected with PRRSV strain VR-2332 and the total RNA was extracted 24Â h post infection for ORF7 copy number detection by real time quantitative RT-PCR.Back to article page
